3 1. PS600 Device-Type The Powers System 600 Controller, from Landis & Gyr, (now Siemens), is supported by the PS600 Device Type drivers in Advantech WebAccess. The PS600 Device driver reads and writes directly to virtual IO Power 600 Controller Module, Protocol Type 2 (P/N ) via the MMI port. This uses and ASCII based protocol, which emulates commands normally used via HyperTerminal. The current version of this driver (July 2005) is limited to reading and writing to virtuals, both Analog and Digital. It has only been tested using virtuals, but it may be able to read and write IO. It will automatically login using any user-defined password. We have only tested with virtual points so we don t know if it can write to IO. There are many features that are not supported, like time, alarm, enable/disable, priority, etc. The read and write capabilities of this driver are equivalent to the following SCU operator commands: Command a Digital Point: Command an analog point value: Login: Log all points in cabinet: PCN ptname PCO ptname PCV Value ptname H Password PL IO Tags A Tag reads only one virtual of a Controller Module (a cabinet). Advantech WebAccess tag names can be up to 21 characters. (Note that the Controller module has tag names that are 6 characters. These will be the address of the Advantech WebAccess tags). Parameters Advantech WebAccess supplies asset of parameters to use as a template for Tag configuration. Two parameters are supplied for building tags. The parameter type must match that of the tag in the Controller (A for Analog Tags, D for Digital tags). User can create their own parameters, but the parameter type must match that of the tag in the controlled (analog = analog, discrete = digital). Version 7.0 rev 0 Advantech Corp., Ltd. page 3

4 Parameter Descrp Part Number Address Start Bit Length A D Analog Virtual Digital Virtual 545/700 Ptname /700 Ptname 0 1 Blocks There are no pre-built Blocks for the PS600 Device Type. A User could easily build a simple block. It would be useful if he repeatedly used lots of IO Modules like it. However, it might be just as easy to build IO tags instead, and more useful, since the tags could have individual tagnames but the same block name is used to reference all parameters of a block. In the ADMIO, the Block Offset should always be 0 if alphabetic characters are used in the ptnames of the controller. This is because the parameter addresses are sequenced by number. 1.1 Serial Connection The PS600 device driver is designed to use a serial connection from the MMI Port on a Controller Module (Protocol 2). The Landis & Gyr controller s MMI Port uses and RJ45 connection. The SCADA node typically has as an RS232 connection. USB to Serial converters are not supported Verify serial connection SCADA node to Controller Module It is recommended to use HyperTerminal (a standard windows component) to verify connection between the SCADA node and Powers System 600 MMI port. Note be sure to stop HyperTerminal session before starting the Advantech WebAccess SCADA node. 1. Start HyperTerminal: Start -> All Programs -> HyperTerminal 2. Enter a name for the session Version 7.0 rev 0 Advantech Corp., Ltd. page 4

5 3. Select OK. 4. Confirm the COM port is correct (typically COM1). 5. Select OK. 6. Modify settings for Baud rate, stop bits, parity, and flow control. The tested device used: 9600, 8 bits, Parity None, 1 stop bit and XON/XOFF. Version 7.0 rev 0 Advantech Corp., Ltd. page 5

6 7. Select OK. 8. The HyperTerminal screen opens. Version 7.0 rev 0 Advantech Corp., Ltd. page 6

The password for the demo system is pangea. 14. >Point, program, Time, Message, Cancel, hardware, Setup, Bye? 15. Enter P. 16. >Log, Display, Command, Monitor, Trend, Operation, Subptlog, Edit, Alarm? 17. Enter L. 18. >Point name? 19. Press the ENTER key (Carriage Return). No entry will list all points in the controller. 20. The report should look like Version 7.0 rev 0 Advantech Corp., Ltd. page 7

The PtNames listed will be used as the address for Advantech WebAccess Tags. If you see the above, he connection works. Otherwise you need to try different baud rates or passwords. Failing that, you should contact the hardware manufacturer s technical support. 1.2 Configure a PS600 Device 1. Open Internet Explorer. 2. Connect to Project Node. 3. Start Advantech WebAccess Configuration. 4. Select Project. 5. Select SCADA Node. 6. Select an Add Comport. 7. Enter the following settings: Version 7.0 rev 0 Advantech Corp., Ltd. page 8

9 8. The comport settings should match those used to test the connection using HyperTerminal. 9. Typical settings are 9600, 8,1,None. 10. The Scan time should be very slow since the interface is a serial one using ASCII characters. 4 seconds for 6 tags. 11. TimeOut should be long (2000 milliseconds). 12. Press Submit 13. Select the Comport (Port 1 in this example) 14. Select Add Device. 15. Select Device Type PS Enter a name for the device. 17. Enter the Password to login to the Controller. This should be the password you used with HyperTerminal at the Hello? Prompt. Version 7.0 rev 0 Advantech Corp., Ltd. page 9

10 18. Press Submit Configure PS600 Analog Tag example This example is to a tag to an Analog Input from a virtual of a PS600 Controller Module. 19. Select Add Tag from Device Properties page 20. From Parameter Pull Down List Select A. This will configure an Analog Tag. Wait for the Page to update. 21. Optionally, select ALARM from the ALARM pulldown list. Wait for the Page to update with a PINK highlight around alarm (an additional Alarm Fields at bottom of page). 22. Enter a Tagname users can use to identify this Analog Input measurement. For example, if this is a Pressure measurement, enter Pressure1. This can be the same as the PtName in the Powers System 600 controller. 23. Enter the ptname from the L&G Controller as the Address. You should see have seen a list of these when you used HyperTerminal to check out the connection. 24. Enter a Description. This will help identify this tag to Users and Operators. For example, enter Boiler #1 Steam Pressure. 25. Optionally enter, Scaling, Span Hi, Span Low, Engineering Units, and Alarms; enable data logging, etc. 26. Press Submit.

11 27. Press Submit Congratulations! You have just configured an Analog Input or Output Measurement from a Landis & Gyr Powers System Configure PS600 Digital (Discrete) Tag example Configuring a Digital Tag is similar to an Analog, except you must use a Discrete type Parameter. In the default driver, this is the D parameter. AN example is shown below. Version 7.0 rev 0 Advantech Corp., Ltd. page 11
